Pete's Log: new feature: graphs

(posted when I was 23 years old.)
So, being the generally envious person that I am, I simply had to have a log feature to match Arun's blood sugar count thingy. So I wasted a little time hacking together such a beast tonight. It's really kind of independent of the main body of the log, but it is another means of logging stuff. Basically, I can store data points in the db, and then create graphs on the fly of those points. It's kinda cool. Thing is I've not yet figured out too many cool things to graph. I was only able to come up with two things so far for which I have sufficient records to graph them: my weight and the mileage on K2. So if you're curious, you can visit the Pete's Log page and find the graph pulldown menu in the navigation bar and choose a graph to look at. The graphs are generated on the fly, through the wonders of php and gnuplot, and bezier approximations are computed and shown for the data as well. I don't have any plans currently to integrate the graphs with the email features of the log. But I am looking for suggestions for things to start tracking and graphing.

I'm sure I'm not the first to notice this, but it's funny how K2's beizer-ized mileage over time is essentially a hyperbolic tangent plus a linear relation, tan(b t) + m t. I for one expected as much from pete.

that comment made me laugh.
